Generate EEAT-Certified Keyword Clusters for SEO Content Optimization and Boost Rankings

You are an expert SEO strategist specializing in EEAT (Experience, Expertise, Authoritativeness, Trustworthiness) optimization for Google rankings.

**Problem (Before):** Manually researching keywords is time-consuming and often misses EEAT signals. Content creators struggle to find clustered keywords that demonstrate real-world experience, deep expertise, authoritative sources, and trustworthy intent, leading to poor rankings and low visibility.

Example Before:
Input: 'best running shoes'
Output: Scattered keywords like 'running shoes sale', 'cheap sneakers' – no structure, no EEAT focus, generic content that doesn't rank.

**Solution (After):** Provide structured, EEAT-certified keyword clusters grouped by themes. Each cluster includes:
- Primary keywords with search intent (informational, navigational, transactional, commercial).
- Secondary supporting keywords (LSI, long-tail) that signal experience (personal stories, case studies), expertise (stats, studies), authoritativeness (citations, experts), trustworthiness (reviews, facts).
- Cluster score: Rate 1-10 for EEAT strength.
- Content outline suggestions: How to weave into an article.
- Competitor gap analysis: Low-competition opportunities.

Example After:
Input: 'best running shoes'
Output:
Cluster 1: Buying Guides (EEAT Score: 9/10)
- Primary: 'best running shoes 2024'
- Secondary: 'running shoes for beginners experience', 'expert tested running shoes reviews', 'top running shoes podiatrist recommended', 'marathon runner shoe case studies'
- Outline: Intro with personal marathon experience, expert citations, trustworthy lab tests.

**Task:** Given the [PARENT KEYWORD OR KEYPHRASE], generate 5-7 comprehensive EEAT-certified keyword clusters.

1. Analyze search intent and volume potential (estimate if possible).
2. Ensure clusters cover diverse angles: beginner guides, advanced tips, comparisons, case studies, FAQs.
3. Prioritize low-to-medium competition keywords.
4. For each cluster: List 4-6 keywords, EEAT rationale, 3-5 bullet content ideas.
5. End with full article outline integrating all clusters.
6. Output in markdown for clarity.

PARENT KEYWORD: [Insert your parent keyword here, e.g., 'electric cars']
